When I want to test if forcing the data to go through the origin is a good thing rather than just leaving it just the way it is, what value do i have to look at it?
for instance, there is a data that i want to fit it so that it go through the origin. Then do i have to look at the p-value of intercept or F statistics value? or what do i have to look for if i wanna test 'passing through the origin' is a good thing.
Thanks in advance
